@munk建议的while循环结束工作。看起来像这样。
#This program ask you to choose a number between 1 and 20, then tries to guess it.
import random
print('Think of a number between 1 and 20, im going to try and guess it.')
print('If my guess is too high or low, please tell me and ill guess again.')
input()
guess=random.randint(1, 20)
answer=input()
print('Is this too high, too low, or correct?')
print(guess)
answer=input()
#answer=input() at end of if statements is necessary to keep them from repeating
while answer != 'correct' :
if answer == 'low':
print('how about now?')
guess=guess+1
print(guess)
answer=input()
if answer == 'high':
print('how about now?')
guess=guess-1
print(guess)
answer=input()
if answer == 'correct':
print('nice!')
print()
print('Press CTRL+C to exit')
